You're correct but mainly because I wasn't paying attention and phrased it as a question. Written instead as a statement, it's a valid counter argument because it's criticizing the parent comment's ridicule of a different instance of criticism.
> Are you saying that EU companies also don't follow their laws?
I'm insinuating that if someone wanted to defend Facebook's position one avenue would be to argue that the law is being selectively enforced. Obviously this isn't a comprehensive argument but it's an easy platform to jump in other directions from.
I doubt a statement expressing dissatisfaction is a valid legal argument responding to a legal ruling. Clearly the term argument in this context is for a legal argument not a colloquial use of the term, since a legal appeal is what is being discussed.
When people get traffic tickets, the judge won't let them off for saying, "But, your honor, the police officer didn't pull over any of the other speeders around me."
That's not a counter argument but dissatisfaction. Are you saying that EU companies also don't follow their laws?
